NEW NEW NEW Latest updates -- 12 April 2016 NEW NEW NEW
  • HIPE 14.1 has been released !
  • Check the important calibration updates and associated improvements expected in the HIPE 14.0.1 and upcoming 14.1 reprocessed data - this includes in particular updated sideband gain ratio in bands 1 to 4
 
  • The HIFI products now come with a frequency-dependent intensity calibration uncertainty budget
  • Channel flags for spurs are now populated in all HIFI observations (this was limited to spectral scan up to HIPE 13)
  • Re-organisation of the HIFI quality flags for a better assessement of issues being relevant or not to the end products

Which data would most benefit from being reprocessed in HIPE 14.0?

Which data would most benefit from being reprocessed in HIPE 14.1 ?

  If your data have been processed with the latest bulk reprocessing (13.0), HIPE 12.0 or HIPE 11.1

  • Spectra mean and median statistical numbers
    • The HIFI 14.0.1 products suffered from a minor bug leading to a wrong computation of the mean and median spectra values (i.e. a measure of the DSB continuum to first order). This has been repaied in 14.1
 
  • Intensity calibration uncertainty
    • HIPE 14 introduces a new product providing an estimated breakdown of the intensity calibration uncertainty. The uncertainties are given separately for each component, as well as in a quadratic sum fashion for all statistically independent elements. This sum applies to the calibration of data in the Ta* scale. Further systematic and random error apply for data converted into different intensity scales (e.g. Tmb or Jy). See further details in section 9 of the DRG.
